The FK BRNO 9mm Conversion Kit (brand part no. FKPSD9KIT) lets an FK BRNO PSD pistol owner train in 9mm Luger instead of the PSD’s proprietary 7.5 FK cartridge, swapping in this kit whenever the 7.5 FK’s higher stopping power isn’t needed for the range session. The kit centers on a 5.3-inch replacement barrel finished with a corrosion-resistant nitride coating, and FK BRNO built the PSD’s auxiliary barrel system so the swap takes less than a minute with no tools or gunsmithing required. Two 9mm magazines ship with the kit, giving the converted pistol a 17-round capacity, and a matched recoil spring is included so the pistol cycles correctly on the lighter 9mm chambering. Because it’s a caliber-conversion kit rather than a full pistol, installation is limited to swapping the barrel, recoil spring, and magazines on a compatible FK BRNO PSD frame. It’s built for PSD owners who want an affordable way to train without burning through 7.5 FK ammunition.
